Hi guys. I am new here and hope i am posting this in the right section. I got out my ipod touch 4th gen(which ive not used in over a year) and had decided i wanted to jailbreak it. I plugged it into my computer and before i knew it, i had inadvertantly updated to 6.1.6. From what i understand, this is more difficult to perform an untethered jailbreak, but not impossible. I have downloaded the firmware numerous times from numerous sites and i, for the life of me, can not get the ipsw from the dmg file. I have tried to use poweriso but get a "this file is not suported" message. Is there anywhere i can get the ipsw file thats already been extracted from the dmg?
